7-panel checklist
Had data + good, had data + bad, reported without pass/fail, or missing. Missing lowers thoroughness — you decide whether that panel matters; PeptIQ’s score still factors coverage.
2 of 7 present · 2 passed · 0 failed · 0 reported · 5 missing
Missing is a thoroughness gap — not automatically bad. PeptIQ’s legitimacy score still weighs panel coverage; you can down-weight panels that don’t matter for your use case.
Identity
Not on this COA · core
Compound identity confirmed (e.g. HPLC, mass spec).
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
Purity
Not on this COA · core
Reported purity percentage for the analyte.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
Heavy metals
Not on this COA
Lead, arsenic, cadmium, mercury, or similar limits.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
Microbial
Tested · passed
Bioburden / microbial limits testing.
No Growth (Bacteria), Not Detected (Fungi/Yeast)
Endotoxin
Not on this COA · core
LAL or chromogenic endotoxin assay.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
Sterility
Tested · passed
Sterility testing where applicable.
No microbial growth detected
Residual solvent / water
Not on this COA
Residual solvents or water content limits.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
How to read this
Had data · good
Panel present with a pass (or clear acceptance).
Had data · bad
Panel present with a fail — a concrete quality signal.
Had data · unclear
Value reported without an explicit pass/fail mark.
Missing
Not on this certificate. Lowers thoroughness; you decide if that panel matters for your use case. PeptIQ’s score still factors coverage.
Findings
Evidence-linked observations from this audit.
Limited scope - sterility only
This is a single-panel sterility screening report, not a comprehensive COA. Missing identity confirmation, purity analysis, heavy metals, endotoxin, and residual solvent testing that are typically expected for peptide quality assurance.
Non-regulatory sterility method
Document explicitly states this is a rapid screening method suitable for QC purposes, and notes that full USP <71> sterility testing may be required for regulatory compliance. This is a preliminary assessment, not a definitive sterility certification.
Batch information present
Lot number TZ202605 clearly documented with sample matrix specified as lyophilized powder.
Same-day turnaround
Sample received and certified on the same date (2026-06-09), which is plausible for a rapid 2-day screening method that may have been initiated prior to formal receipt documentation.
Lab verification not possible
Kovera Labs is named as the testing facility, but no website URL, accreditation information, or independent verification method is provided beyond a QR code access code (EB005D).
Professional presentation
Document has clean, professional formatting with clear sections, proper branding, and includes a photograph of the tested vial showing batch number consistency.
Incomplete for peptide COA standards
While legitimate as a sterility screening report, this would be insufficient as a standalone Certificate of Analysis for a research peptide. Identity and purity testing are fundamental requirements missing from this document.
